Library Description

The library includes features to enable or disable devices and functions to check if the input voltage is below the operating voltage.

Key functions:

• void buckboost3_enable(uint8_t state) - Function for enable/disable device
• uint8_t buckboost3_getInterruptState() - Function for get Intterupt pin state

Examples description

The application is composed of the three sections :

• System Initialization - Sets INT pin as INPUT and CS pin as OUTPUT
• Application Initialization - Initialization driver init and enable device
• Application Task - (code snippet) - It checks if the input voltage is below the operating voltage.

void applicationTask()
{
    uint8_t PGOOD_state;
    
    PGOOD_state = buckboost3_getInterruptState();
    if (PGOOD_state == 0)
    {
        mikrobus_logWrite(" Low input voltage !!!", _LOG_LINE);
    }
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• GPIO

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
